品位、厚度是衡量矿体质量和形态规模的主要标志,其变化性对矿床勘探有很大影响。因此,详细研究品位、厚度的变化性,已成为勘探中每一个阶段的一项重要任务。矿体的变化性包括变化性质、变化程度及控制矿体变化的地质因素(变化原因)三个不可分割的基本要素。可是,长期以来,人们研究变化性往往只注重变化程度。如研究矿体品位变化,常划分出均匀的、不均匀的两类,或细分成三至五类。又如研究矿体厚
Grade and thickness are the main indicators to measure the quality and shape of the ore body. Its variability has great influence on the exploration of the ore deposit. Therefore, a detailed study of variability in grade and thickness has become an important task in every stage of exploration. The variability of the ore body includes three indivisible basic elements: nature of change, degree of change and geological factors that control the change of the ore body (causes of change). However, for a long time, people tend to focus only on the degree of change in the study of change. Such as the study of ore grade changes, often divided into uniform, non-uniform two categories, or subdivided into three to five categories. Another example is the study of ore thick
